Abstract Information :
Hazardous areas, where concentrations of flammable gases, vapours, or dusts can be present, provide some of the greatest safety challenges across facility design, construction, and installation, especially when installing electrical equipment. This applies equally to analyzers such as continuous emissions monitoring systems (CEMS), where the specifics of gas sampling do not make it practical to install the system in a safe, non-classified area. With multiple protection options for electrical equipment, engineers must determine the most cost-effective method to mitigate the risks, while ensuring compliance with the applicable certification schemes and standards, such as ATEX, IECEx, and NFPA. The paper will provide a brief overview of hazardous areas and compare potential protection methods for continuous emissions monitoring systems. Using real analyser case studies, we will discuss problems with different gas sample types, and highlight possible solutions and options for successfully gaining certification with reference to the IEC standard 60079-2.
